Application tiled January 8.1906- Serial No. 295.031.

Be il known that l, Mounts l". Jtxmuc'r'r, a ritizen ol' the llnited States, residing at Anderson, in the eounty ol Madison and State oln Indiana, have invented certain new and usel'ul lmprovements in Ann ailing-Boxes, ol whirli ille. lollowing is a speeilieai ion.

ln the manul'avtiu'e oll tin and other simiz lar plate the blaeh plaies alter having been rolled are subjeeied to sullieient heat to anneal them, and lor this Apurpose they are placed in staeks ol a suitable number ol' plates, earh staek being rovered by an airtight box, so that the plates will be subjeeted to the desired heat without beeoming oxidized. Snell boxes heretol'ore have been made ol' a strip or sheetV olI metal bent to l'orm the l'our sides oll a box, the iop being l'ormed by an inrerteil-eup-shaped plate, the edges oll which are downturned and lap over the upper edges oll the side walls ol' the box, the paris being welded together in that posif tion. In sueh a box it is l'oundtthat in I eourse ol. time the entire top is eaten away by the llames and the side walls arfe eateinaway pist below 'the lower edge ol the to'p and the top is burned out at the point'I where its edges l are downiurned.

Figure l is a perspeetive view ol. my improved box; Fig. 2, a transverse section.

l i l In the drawings, li) indicates the side walls g l' the box,said side walls being lormed u1 the j usual manner ol' a single sheet bent to l'orm the l'our walls. 'lhe top ol my box consists ol' a sheet ll, wliieh is rupped to l'orm upturned edges l12 ,whirhlt inside. oll the upper ends oll the side walls l0 and are Welded thereto, the top thus forming a cup 13, in whieh ma) be placed a sufficient layer or body ot' sand to properly protect the top of the box, this layer of sand protecting the bends i4- ot' tho eap and leaving exposed only the upper edges oll the side walls and the rap edges l2.

By this arrangement it becomes much more easy to weld the parts l2 to t'ne upper edges ot the side walls 1i), and the exposed upper edges may be eaten away Very considerably without destroying the usefulness otl the box. As a l'urther protect-ion for the upper closed end ot' the box I weld to the outside ol' the walls lt), ai. the upper edges there of, a band lli, said band extending down below the adjaeeni portions ol the cap 1I.

In the drawings l have shown the metal portion oll eap ll arched upward and supported by an internal brace member 17, which is seeured to the inside olI the Walls 1() in amy suitable manner, i

The band i6 should properly be beveled at MORRIS F. JARRETT. [1). s.]
